Civil Engineering QUESTION #6623
Question 1
The 'Modulus of Elasticity' ($E$) for all structural steel grades is approximately:
  • $29,000,000$ psi✔️
  • $2,900,000$ psi
  • $290,000$ psi
  • $50,000$ psi
Correct Answer Explanation
Unlike yield strength, the stiffness of steel ($E$) is constant across nearly all grades, taken as 29,000 ksi or 200,000 MPa.
